Christopher.... You do not beat stock bikes... unless you mean those Katana 300's or whatever they are. A 600, even a weak 600, with a 300lbs man on the bike, would decimate you. The best your car runs AS IT SITS is a 13.5. I know NO bikes that run that slow, even stock. Maybe a harley or something? Or a goldwing...

But no crotch rockets.
